/** I got a telescope for Christmas when I was about 6 years old.  I pointed it
    out the window and the very first bright "star" I focused on turned out to
    be Saturn!  What are the odds?  This program calculates the position of
    Saturn every Christmas about 8 PM to verify my recollection.
